# azure-app-onboard-prereq

Assesses source code readiness before initiating Azure infrastructure deployment. It checks dependencies, frameworks, and tools without running build commands.

## What it does

The skill handles the initial phase of the AppOnboard pipeline. It inspects repository structure, identifies runtime stacks, and checks whether local binaries like `az`, `azd`, and `func` are available. Output verdicts are written directly to `prereq-output.json` with PASS, WARN, or FAIL statuses for each component.

Package manager commands are prohibited during evaluation. The tool never executes `npm install`, `dotnet build`, or `pytest` while analyzing readiness. It relies strictly on static inspection. When third-party cloud SDKs like AWS or Google Cloud are detected, execution halts until you approve continuing or redirecting to migration.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-app-onboard-prereq -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-app-onboard-prereq/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-app-onboard-prereq/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-app-onboard-prereq/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-app-onboard-prereq/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-app-onboard-prereq
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-app-onboard-prereq/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-skills/skills/azure-app-onboard-prereq
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-app-onboard-prereq/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-skills/skills/azure-app-onboard-prereq/SKILL.md

## When to use it
- verify if application code is deployable to Azure
- detect third-party cloud SDKs and conflicting dependencies
- check availability of required CLI tools like az and azd
- record component readiness statuses in prereq-output.json

## Example prompts
- Evaluate this repository for Azure deployment readiness
- Check my app configuration and dependencies for Azure blockers
- Scan my project to see if I need a Dockerfile for Azure

# Azure App Onboard Prereq — Repository Evaluation

Evaluate a user's repository for build health, app completeness, and Azure deployment feasibility — before infrastructure planning. Produces per-component verdicts (PASS/WARN/FAIL) consumed by downstream phases.

> **Orchestrator relationship:** Called by `azure-app-onboard` at Step 3, or standalone for code readiness checks. When called by orchestrator, return control to `azure-app-onboard` after writing artifacts — do NOT invoke downstream phases directly.

Phase 1 of 4 in AppOnboard pipeline. Session: `.copilot-azure/sessions/{session-id}/`. Reads `context.json`. Writes `components[]`, `repo{}`, `detectedInfra[]`. Produces `prereq-output.json`. Schema: [`prereq-schemas.ts`](references/prereq-schemas.ts) — `PrereqOutput`, `BuildRequirements`. Direct entry supported.

## When NOT to Use

| Signal | Redirect |
|--------|----------|
| Validate infrastructure (Bicep/TF/azure.yaml) | **azure-validate** |
| Generate IaC | **azure-prepare** |
| End-to-end idea-to-production | **azure-app-onboard** |
| Run `azd up` or deploy | **azure-deploy** |

## Rules

> ⛔ **ABSOLUTE PROHIBITION — `npm install`, `npm test`, `npx jest`, `pytest`, and ALL install/build/test commands are NEVER allowed.**
> Under NO circumstances may you run `npm install`, `npm test`, `npx jest`, `pip install`, `pytest`, `dotnet build`, `dotnet restore`, `dotnet test`, `go mod download`, `cargo build`, or ANY package-manager install, build, or test command during the prereq phase. Do NOT run test suites to verify code — check for test config files statically instead. The prereq phase is read-only evaluation + static-only verification.
> **ONLY exception — two sanctioned contexts, both consent-gated:** (a) code the agent **modified** during migration/remediation (see [remediation-protocol.md](references/remediation-protocol.md) step 6), or (b) code the agent **wrote** from scratch on the zero-code path (see [zero-code-path.md](references/zero-code-path.md)). In either case, install/build/test runs ONLY via the user-confirmed build-validation gate ([build-check.md](references/build-check.md) Step 3), after the user answers that specific per-command consent prompt. General prior consent never counts.
